Abstract: A filter seal (141) for a cylindrical air filter (140) includes a polyurethane member which is configured with two primary portions (141a, 155). One portion (141a) is an annular body which is formed with an annular receiving channel (154), which is sized to receive one end of a corresponding filter element (142). The other portion (155) is an annular sealing lip disposed in spaced relation to the receiving channel (154). This sealing lip includes a ribbed, radial-sealing surface and a convex, axial-sealing surface (164). The radial-sealing surface provides sealing contact with an outlet portion of the housing by means of tension while axial sealing is achieved by compression of the axial-sealing surface against a generally planar surface of the housing. In addition to these two modes of sealing engagement, differential pressure forces cause the sealing lip to press tightly against the housing to enhance the sealing.

Abstract translation: 用于圆柱形空气过滤器（140）的过滤器密封件（141）包括构造有两个主要部分（141a，155）的聚氨酯部件。 一个部分（141a）是环形主体，其形成有环形接收通道（154），其尺寸适于接纳相应的过滤元件（142）的一端。 另一部分（155）是与接收通道（154）隔开设置的环形密封唇。 该密封唇包括肋状的径向密封表面和凸形的轴向密封表面（164）。 径向密封表面通过张力提供与壳体的出口部分的密封接触，同时通过将轴向密封表面压靠在壳体的大致平坦的表面上来实现轴向密封。 除了这两种密封接合方式之外，差压力使得密封唇紧紧地压靠在壳体上以增强密封。
